PC fails to boot during POST

Hello. I having troubles with my PC booting every once in a while. When I turn it on, it seems to work for about 2 seconds, (during this time, the monitor is ON, and no POST screen shows up (AmiBios) and then it starts with 4 short beeps, about 2ms each. After that, it moves to 3 continuous beeps, about 3ms apart, 1 second each. I am not sure what could be causing it.

The solution to this problem is to get a hairdryer, and use it to blow hot air into the CPU (case off) for about 30 seconds to 1 minute. After this, the PC POSTs just fine and boots into Windows. Any idea on a LONG term solution? I am fed up with having to get out the hairdryer every time I want to use the PC.


NOTE- The PC usually does this whenever it has rained in the past 24hours. The PC is about 2 meters or about 7 or 8 feet away from the physical window, under a desk, on a little cart/stand. It has good ventilation,

If you need specs, I will try to get them, however, I am not very positive of what is in this PC other than it runs WINDOWS XP, has 256MB of ram, and has Intel Pentium 4 at 1,9GHz

Possible problem...
  • 4 short System timer failure
  • Overheating issue.


Since using a blow dryer to blow air into the case seems to work I would suggest checking the fan on the cpu to make sure it is working.
